    5 Power stage The DC voltages required at various parts of the chassis and panel are provided by a main power supply unit. This chassis can operate with the different supplies: IPS60, IPS16, IPS17, PW26, PW27 as main power supply and also with 12V adaptor. CN706 is used for IPS60, IPS16 and IPS17 and CN1 is used for PW26 and PW27.
  • Page 19 The blocks on power block diagram is using dependent to main supply. For PW26 and PW27 just common blocks are enough for proper operation. For IPS16, IPS17, IPS60 below blocks must work properly. For adapter case also below blocks are necessary.
